If you need the Onan manuals for the MDJE, PM your email address to me and I will send them too you.
I have the manuals, thank you.

I should have mentioned, it's the raw water pump, not the circulating water pump. Both are belt-driven off the flywheel.

I can't seem to find the flow rating for the existing part, Onan 170-3172, or its replacement, 131-0257.

I've seen the Depco site, I may call them Monday just to see what they say.

$1500 for a new pump is out of the question. I'm interested in the idea of an electric pump. I'm actually surprised that isn't done more, given how unreliable and problematic rubber belts and impellers seem to be.

I also think those who say to just clean it up and use it, since it's showing no other signs of failure, may be onto something.
